Construction Material Costs: By the Numbers
- ~$150/yd³ — average ready-mix concrete delivered price in the US (2026)
- 1 yd³ = 27 ft³ — the volume conversion at the heart of every concrete calculation
- 5–10% waste factor — standard for most construction material estimates
- 350 sq ft — average paint coverage per gallon (single coat, smooth surface)
- ~$1.50–$3.50/sq ft — typical asphalt shingle roofing cost installed
- 1.4 tons/yd³ — standard weight of crushed gravel for delivery estimates
- 16" on center — the most common framing and stud spacing in US construction
